Objective: To determine maternal and fetal outcome in pregnant women with relapsing polychondritis (RP).
Methods: Retrospective review of 11 records selected from among those of 116 female RP (Michet's criteria) patients.
Results: In these 11 women, 25 pregnancies occurred after or concomitantly with the onset of RP. The mean (+/- SD) age at RP onset was 25 +/- 5 years (range 15-31). Therapeutic abortion was performed in 1 woman because of ongoing cyclophosphamide treatment. Disease flare occurred in 7 of 24 pregnancies, requiring treatment modification in 2 cases. RP was considered stable in 16 and asymptomatic in 1 of the 24. Treatment of RP was with nonsteroidal antiinflammatory drugs (2 of 24), steroids (13 of 24), dapsone (7 of 24), or plasma exchanges (1 of 24); no treatment was given in 8 of the 24 pregnancies. In 14 pregnancies, the course was uneventful. Ten pregnancies were complicated by ectopic nidation (n = 3), spontaneous abortion (n = 3), premature birth (n = 3), and premature rupture of membranes (n = 1). Eighteen normal children were born.
Conclusion: Pregnancy does not seem to modify the course of RP. Successful pregnancies may be achieved in women with RP. No RP was observed in the neonates.
